This has legs because it leverages cheap, ubiquitous technology with the added layer of ultra-low-power sleep mode. This allows for a lower time to profit for this company because they do not need to subsidize the cost to ramp up volume, or at least not as much.

Can this be used to hand-off phone calls and video-data on cell phones to a in building DECT-ULE to back-haul to free up valuable cell phone frequency bandwidth?
If so partner with the cell phone companies in a win-win arraignment.
BW is more valuable than gold in some areas right now and will be a mushrooming problem.

Now get the smart phone manufactures to put these chips into heir new offerings. My father just had a stroke, and this morning I saw that in Australia they have done a study that stroke patents risk of death during recovery (another stroke, impaired thought that can lead to low blood sugar...)
1) temperature monitoring
2)blood glucose levels
3)ability to swallow (this one not applicable to the idea here anyway, needs to be observed.)
Now add a watch with any of the above LAN/PAN (inluding DECT-ULE) choices that can detect 1 temp, 2) glucose through the skin in the back of the watch or in the wrist strap and create an app that alerts the patent to eat get warm, add a function that by default must be acknowledged by patent and condition improves by patent intervention. if no acknowledgment is received cell phone calls 911 by default, can change to doctor, nurses station, care giver, etc. If condition is not changed within short-given time frame 911 or nursing station 911 alert sent out by cell phone.
I want to do this so bad now because of the motivation of my fathers stroke, but I can't break into the medical or wireless field HR department stupid keyword search has locked me out...Help!
